On  January 25, 2006, the Board of Directors ("the Board") of Harleysville Group
Inc.  ("the  Registrant")  approved  amendments  to the following benefit plans:

     The  Pension  Plan  of  Harleysville  Group  Inc.  and  Associated
     Employers Amended and Restated as of January 1, 2003 (the "Pension Plan");

     The  Harleysville  Group  Inc.  Supplemental  Retirement  Plan  (the
     "SERP");

     The  Harleysville  Group  Inc.  Extra  Compensation  Plan,  now  known  as
     Harleysville  Retirement  Savings  Plus  Plan  (the  "Retirement
     Plan");  and

     The  Harleysville  Group  Inc.  Non-Qualified  Excess  Match  Plan,  now
     known as Harleysville Excess Contribution and Match Program (the "Excess
     Plan").

The Registrant announced the changes to the Pension Plan and the Retirement Plan
in  a  press  release  dated January 26, 2006 which is attached as Exhibit 99.1.

In  addition,  the SERP was amended to "freeze" benefit accruals as of March 31,

Revenue  Code  section  409A.  The SERP was amended to specifically provide that
the  Board  may  not  amend  the  Plan  to  accelerate  payments  from the SERP.

In  connection  with the changes to the Retirement Savings Plan, the Excess Plan
was  also  amended  as  of  January 1, 2006, to provide for a bi-weekly employer
contribution  of  5%  of base salary paid that shall vest in accordance with the
terms  of  the  Retirement  Plan.
